How this service works
The independent gate before a merge, deploy, or payout. Deterministic JavaScript (Node) or Python 3 run against a contract or claim; returns HELD, BROKE with the failing input, FINDINGS, or DROP. BROKE requires a contract. Ephemeral sandbox, nothing stored. 0.10 USDC; allow up to 120s.
Output
A verdict string: HELD (the function satisfies the contract or assumption), BROKE (a specific failing input is returned that violates the contract), FINDINGS (insights from plain-language assumption analysis), or DROP (the request could not be evaluated). The response is returned after up to 120 seconds of sandboxed execution. Nothing is stored.
Example use cases
Example prompt
“Verify this Python function against the contract I have — the function is supposed to always return a sorted list, and I want to know if it ever breaks with a counterexample: [paste code and examples].”
Technical details
Endpoint
GEThttps://kenoodl.com/api/verifyWhen to prefer
Use this endpoint when you need a formal correctness verdict on a JavaScript or Python function — especially when you want machine-checkable proof that a function holds or breaks against specific input/output examples (contract mode), or want exploratory analysis against a natural-language assumption (assumption mode). Prefer this over static analysis tools when you need dynamic execution with a binary HELD/BROKE result and a concrete failing witness.
Side effects
- DROP returned if the code cannot be evaluated or the request is malformed
- Timeout after 120 seconds with no verdict
- BROKE only fires when a formal contract is provided — plain-language assumptions yield FINDINGS or HELD, never BROKE
- Code exceeding 16,000 character limit rejected
- Payment failure if wallet has insufficient USDC balance
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| code | string | The function source under test. |
| contract | object | Provide a {fn, examples:[{call, expected}]} contract for a BROKE-capable verdict. BROKE fires only from a contract you provide. |
| assumption | string | A claim about the code in plain words, for a FINDINGS read (never BROKE). |
